This paper addresses the application of a recently developed agricultural productivity equation for predicting reclaimed surface mine soil's ability to support neo-sol plant growth potential for a sand and gravel surface mine in Clay County, Minnesota. Four reclamation treatments were evaluated for their ability to improve plant growth: removing rock fragments and grading the post-mine landscape to a 3% slope, soil compaction, increasing organic matter and electrical conductivity, and saving the topsoil. All treatments increase soil productivity rating (p<0.05), Removing rock fragments and grading the post mine landscape to a 3% slope were the most effective and cost efficient reclamation approaches for the case study at the Spillum mine site. |
